When it debuted, the Segway was supposed to start a new revolution in transportation in the same way inventor Dean Kamen's other inventions revolutionize health care. Unfortunately, his other inventions didn't so much revolutionize health care.
Like his other inventions, the Segway's high cost has kept it away from most private citizens, meaning the device is more likely to be seen in the arms of a security officer in Millennium Park than John Smith's garage.
Kamen told CNN it's been rough going:
"You end up lying there saying, 'I'm not stopping. It would be an act of shallow cowardice. Or you decide to quit and you say, 'This is one of those ideas that just isn't going to work,' "
While we've never been moved by the Segway — the novelty wears off after a while — it's worth a shot and could easily be the failed design which gives way to products like the Toyota Winglet — which may someday see success.
